For classes who rely on energy regeneration such as Rogues, things have also changed significantly since the classic era. Regeneration used to occur in chunks based on the server “heartbeat.” So, to gain 20 energy, it would take a full two seconds. Today, the system is smoothed out so that that 1 energy regenerates every tenth of a second. This difference changed the timing of being able to use certain abilities. What seems like a minor convenience today actually changes the very flow of combat rotations and burst capabilities in classic gameplay. We felt this was important to restore to provide this authentic experience.
Rogue combo points posed another challenge, because the game’s modern resource system knows how to gain and spend combo points, but not how to lose them when changing targets. There are also the older combat formulas to consider, so we had to bring back the code for the prior combat formulas including critical hits and crushing blows. Their chance to occur is also modified by the difference between the defender’s defense and the attacker’s weapon skill. Yes—weapon skill is back. We had the data for this aspect of the classic game, but we also needed to restore the code that increased your skills when you used them and made your skill level affect your chance to hit or get a glancing blow.

Now that you know to loot everything (see tip #1), you’ll have a lot of items in your bags. Any item that is white quality or greater may sell on the Auction House. How do you know what will sell well on the auction house? Trade goods and green quality (or better) items will almost always sell on the Auction House. See our Auction House guide (coming soon!) for more information.

Nov 15 Dual Boxing in Classic I was seriously thinking about being a masochist and playing a paladin in classic but then I wondered if dual boxing will still be possible in classic with the change in engines running the game. I've never dual boxed so will have to research how it works. However, it hit me that I can dual box a warrior and a priest then transfer the priest to my main account at 60 so I will have the best tank and best healer in the game to play around with. Anyone else planning on doing this and have any good resources to start learning about it?Twiinkedd6 Nov 15
This was a good start, but there were issues with how the developers used to handle updates to the database data. Unlike the source code, for which Blizzard had archives for multiple branches of the game that could be worked on and developed as separate pieces, early database data was overwritten with each commensurate update. Thankfully, that problem was fixed very quickly after launch, and when we looked, we found data going back to version 1.12—and even earlier.
Earning gold in World of Warcraft: Classic is all about optimizing your spendings. Back in the day, your character’s skills were acquired from a trainer, using money. Don’t just buy everything he or she offers! Read the skill descriptions and be mindful about them. Quite a few characters can live through the levelling process without learning some of their utility or damage spells. These won’t go anywhere and you’ll be able to learn them later on.
Another hurdle we had to overcome was how to store and merge our data. World of Warcraft has multiple updates or patches in development at any one time, each in a different stage of development. If an art asset or terrain file is added to one patch, the system is designed so that it also automatically shows up in later patches. This meant that If we had simply inserted a new patch for WoW Classic into the current development environment, we would have overwritten things like the current broken dam in Loch Modan with the previous intact version—and as you can imagine, this would have caused issues for Battle for Azeroth.

A demo of the game was available at BlizzCon 2018, and was downloadable on home computers for anyone who purchased a BlizzCon ticket or virtual ticket. The servers became available when Opening Ceremony started at BlizzCon 2018 and was set to end on November 8, but was extended until November 12.[4] Players started at level 15, and the only available zones were Westfall and the Barrens.[5] It was based on patch 1.13.0, essentially patch 1.12.0 ported to a modern infrastructure. The first day of the demo, there was a playtime limit of a cumulative 60 minutes with a cooldown of 90 minutes, applied through the BlizzCon Exhaustion debuff.[6] The debuff was removed on the second day of BlizzCon 2018.[7]
